IDOL HELP, & MX-5

[1lowufo]

NEED SOME HELP, HAVE AN O1, AND GAVE IT NEW 'CHAMP' DOUBLE PLAT. PLUGS (GAP 45), NEW 'MEG.' 8.5 WIRES, AND A NEW 'SCREAMIN DEAMON' COIL. AT THE SAME TIME, DID THE MX-5 MOD. CAR RUNS LIKE A PRO STOCK W/O THE AIR. WITH THE AIR ON, MY IDOL IS EVERY LOW (5-6), ALMOST WANTS TO STALL. NEVER HAD THIS BEFORE THE TUNE-UP. SHOULD I RE-GAP THE PLUGS TO 50 OR 55? AND WOULD THIS EVEN MAKE A DIFFERENCE? AS FOR THE MX-5 MOD, I LOOKED FOR 5 MINUTES AND FOUND NO 'YELLOW& GREEN' WIRE. THE ONLY YELLOW I FOUND WAS WITH A BLACK (NOTHING GREEN LIKE IN THE PICS) SO I CUT AND TAPED IT THINKING MAYBE THEY RAN OUT OF YELLOW/GREEN WIRE...REALLY CAN'T SAY I NOTICED ANY REAL DIFFERENCE. AT FIRST AFTER THE TUNE-UP THE 'CHECK ENGINE' LIGHT WAS ON, BUT IN ABOUT A MILE OR SO WENT OUT. ANY THOUGHTS WOULD REALLY PUT MY MINE AT EASE. THANKS!

Chrysler doesn't "run out" of yellow/green wire. I haven't the faintest idea which wire you cut...but it's the wrong one. Why not tape it back together and see if your problem stops?

[MX-5]

You certainly cut the wrong wire.

Pin49 K60 20YL/BK IDLE AIR CONTROL NO. 2 DRIVER

That is the idle control driver circuit from pin 49 of the PCM to the IAC solenoid.
See page 8W-30-7 of the service manual wiring diagrams.

Re-connect the circuit, and you should regain your idle control.

THANKS GUYS FOR THE INFO! IS THE GREEN/YELLOW WIRE BURRIED IN THE WIRE MASS. I'LL LOOK AGAIN, BUT I REALLY COULDN'T FINE A GREEN/YELLOW. SHOULD I DISCONNECT THE BATTERY AFTER I RE-CONNECT THE YELLOW/BLACK TO RESET THE COMPUTER?

Taylormade, read his post, he owns a 2001. No need to be his thesaurus.

Please do everyone a favor and never work on another car again. Thanks.

(Probally a little harsh... but come on, you just don't go cutting random wires)
